HARRY R. LELAND, OF PABKERSBURG, WEST VIRGINIA, ASSIGNOB. T0 THE RARKERS- B'URG RIG & REEL COMPANY, OF PARKERSBURG, WEST VIRGINIA, A CORPORATION OF WEST VIRGINIA.

GAS AND LIQUID SEPARATOR.

Application filed October 14, 1920.

To all whomit may concern:

Be it known that I, HARRY R. LELAND, a citizen of the United States, residing at larkersburg, in the county of Wood and State of West Virginia, have invented certain new and useful Improvements in Gas and Liquid Separators, of which the following is a specification.

llhis invention relates to gas and liquid separators, and it comprises a closed tank having means for delivering gases and liquid thereto, a trough arranged within the tank and extending circumferentially and clownwardly, said trough being open at the top, a gas collector comprising a pipe or tube arranged within the tank and connected to a suitable outlet, and bafl'les arranged in said tube to collect any liquid contained in the gases passing through said tube.

In oil producing fields, the oil as it leaves the well is pumped into a flow tank whence it is delivered to storage tanks. As a general rule, this oil contains a certain amount of gas which, in escaping therefrom, has a tendency to carry off considerable volume of oil in small drops or globules giving a misty appearance over a tank into which oil is being pumped. I have found that if the oil is spread out into a thin layer having a comparatively large surface, that the escape of gas is not so violent and that the tendency to carry oil' oil is thereby diminished. The oil carried oil in the form of a vapor or mist is generally the lighter low boiling fractions which are more valuable than the heavy components of the oil and and loss incident thereto is greatly increased.

providing a trough within a tank and causing the oil to flow through this trough for a considerable distance before it is de' posited into the body of oil in the bottom of the tank, I have found that the loss of low boiling constituents, in connection with the liberation of the gases in the oil, is greatly reduced. I have also found that the loss can be reduced to a minimum by assin the gases immediatel throu h a p b r: to

closed tube having baliles or other means for restraining the flow of gas and collecting any oil contained therein, the oil being conveyed to the body of oil in the bottom of the tank.

In the accompanying drawings, I have Specification of Letters Patent.

Fig. is a detail sectional View of the tube.

Referring to the drawings, the reference numeral 1 designates generally a tank constructed in the manner described in my copending application, Serial No. 423,291, filed November ll, 1920, in which the deck of the tank is made absolutely gas tight. The tank is provided with a deck 2 supported on rafters 3 and having a manhole opening i arranged therein. The oil and gas to be separated are delivered to the tank through a feed pipe 5. A trough 6 is arvinged within the tank, the trough being preferably arranged in the form of a spiral as shown, and being supported from the side of the tank by brackets 7 as shown. The upper end of the trough immediately beneath th feed pipe is enlarged. as at 8 to prevent the oil l'IOIll splashing over the side of trough into the bottom of the tank. The oil passing from the trough is delivered ii'rom the bottom of the tank as indicated at 9, and is continually withdrawn there-from through an outlet opening 10 by suitable means (not shown). A gas collecting tube 11 is arranged within the tank, the tube comprising a substantially rectangular body portion arranged in horizontal sections 19;, 1.3, and 14:, connected by vertical sections 15, l6, and ll. The lower horizontal section is provided with an enlarged tunnel shaped mouth 18 through which the gases enter. Each of the horizontal sections is inclined downwardly toward the outlet and is provided at its lower end with an opening 19 whereby oil collected may be delivered to the bottom oi. the tank. A plurality oil ballles 20 are arranged within the tube the battles being secured to the side walls there of. Any suitable means may be employed for securing the battles in position, and I have shown one means wherein ears 21 are arranged on the ed es olthe battle plates adapted to receive suitable fastening'means to secure them to the Walls of the tube. As shown, the balfies are spaced at their lower ends from the bottom of the tube to permit flow of oil, deposited on the plates to the openings 19.

Theupper end of the vertical section 17 is connected to a cap or cover 9 arranged in the manhole opening. This cover is provided with a centrally arranged opening communicating with apipe. 23 arranged on the cover. The exhaust pipe 23 is provided with a. hinged. cover 24 having a Weight 25 to normally maintain it in open position. A cord 26, is connected to the end of the cover whereby it may he closed when desired.

The tanlr is. provided with the usual lflf der :27 and the horizontal sections oi the gas collecting tube are passed between the legs 28 and29 of the ladder and rest on one of the rungs (see Fig. 3).

In operation, the gasecontaining oil is delivered to the tank through pipe 5 into theupper end 8 of the trough 6. The oil flows downwardly in the trough in a spiral path and is delivered to the bottom of the tank as indicated at 9. During its passage b ugh the trough, the increased surface provided permits-the gas to separate from the oil more gradually than if the oil We pumped into the bod of oil in the bottom of the tank. The. escaping enters the tube 1i through. the funnel shaped opening 18, the body of oil in the bottom of the tanlr being always maintained below the opening 18. In passing through the collecting tube the gas is continuallybrought into contact with the. battles 20. and any oil contained in the gas is deposited on these baflies. The oil collecting in the tubes passes down the in clined bottom to the openings 19 whence it is delivered to the bottom oi the tank. The gases passing through the outlet pipe 23 are delivered to the atmosphere or to any suitable container.

.t is to be understood that While I have described the. preferred embodiment of my invention, various changes in the shape, size, and arrangement of parts may he made Without departing from the spirit of the invention or the scope oi the suhjoined claims.

Having thus described my invention, I claim:

A liquid and gas separator comprising a closed tank. means for delivering the liquid and gaseous mixture into the tank, a collecting tube provided with an outlet and an. enlarged inlet, said l'llllc comprising slightly inclined sections and Y'rllfl'll'lli connecting sections. said inclined sections being inclined downwardly in the direction ol lion of the and prorided with outlets at their lowest points, and h.

aiiie plates arranged in said tulle to col ec. tained in the gases.
